摘要
从倾斜光纤光栅(TFBG)着手,首先介绍了TFBG的主要特点及其应用,分析级联倾斜光纤光栅(CTFBG)的结构和优点。在TFBG的理论基础上,用传输矩阵法对CTFBG进行理论推导,利用OptiGrating软件对CTFBG进行数值模拟仿真,主要研究倾斜角度、级联数目和光栅间距对CTFBG光谱特性的影响,着重分析了CTFBG在传感方面的应用。
Starting from the tilted fiber grating （TFBG）, this paper introduces the main features of TFBG and its application, analyzes the structure and advantages of cascaded tilted fiber gratings （CTFBG）.Based on the theory of TFBG, the cascaded tilted fiber Bragg grating （CTFBG） is deduced by transmission matrix method. The numerical simulation of CTFBG was carried out by OptiGrating software. This paper mainly studied the influence of tilted angle, cascaded number and grating spacing on the spectral characteristics of CTFBG, and analyzed the application of CTFBG in sensing.
